Question

我有JSON数据。我使用Newtonsoft.Json进行反序列化

{
    {
        "id":"951357",
        "name":"Test Name",
        "hometown":
        {
            "id":"12345",
            "name":"city"
        },

        "bff": [
            {
                "people": {
                    "id":"123789",
                    "name":"People Name"
                },              

                "id":"147369"
            }
        ],

    }
}

我创建了类：

 public class Data
{
    [JsonProperty("id")]
    public string Id;

    [JsonProperty("name")]
    public string Name;

    [JsonProperty("hometown")]
    public string[] Hometown;

    [JsonProperty("bff")]
    public Bff[] Bff;
}

public class Bff
{
    [JsonProperty("people")]
    public People[] People;

    [JsonProperty("id")]
    public string Id;
}

public class People
{
    [JsonProperty("id")]
    public string Id;

    [JsonProperty("name")]
    public string Namel
}

public class Hometown
{
    [JsonProperty("id")]
    public int Id;

    [JsonProperty("name")]
    public string Name;
}

但是如果我打电话的话 Data datatest = JsonConvert.DeserializeObject<Data>(data); 在哪里＆＃34;数据＆＃34;它的json数组我有这个错误：

最佳重载方法匹配＆＃39; Newtonsoft.Json.JsonConvert.DeserializeObject（字符串）＆＃39;有一些无效的参数

问题在于：

"hometown":
{
    "id":"12345",
    "name":"city"
},

在映射类期望数组时传递单个对象：

[JsonProperty("hometown")]
public string[] Hometown;

执行：

"hometown":
[{
    "id":"12345",
    "name":"city"
}],

另外：

同样的问题是没有将其作为[]

People

拥有Hometown类型的string[]属性，而不是Hometowm[]
你的json

{}

这是有效的JSON：

{
    "id":"951357",
    "name":"Test Name",
    "hometown": [{
        "id":"12345",
        "name":"city"
        }],

    "bff": [{
        "people": [{
            "id":"123789",
            "name":"People Name"
        }],
        "id":"147369"
    }],
}

有效代码：

public class Data
{
    [JsonProperty("id")]
    public string Id;
    [JsonProperty("name")]
    public string Name;
    [JsonProperty("hometown")]
    public Hometown[] Hometown;
    [JsonProperty("bff")]
    public Bff[] Bff;
}

public class Bff
{
    [JsonProperty("people")]
    public People[] People;
    [JsonProperty("id")]
    public string Id;
}

public class People
{
    [JsonProperty("id")]
    public string Id;
    [JsonProperty("name")]
    public string Name;
}

public class Hometown
{
    [JsonProperty("id")]
    public int Id;
    [JsonProperty("name")]
    public string Name;
}

如何反序列化这个json数据？
